GAS HEATING APPARATUS.

Patented May '26, 1908.

Application filed April 22, 1907. Serial No. 369,693.

To all whom it may concern:

Be it known that we, HIRAM G. STEELE and JOSEPH J. WILLY, citizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Gas Heating Apparatus; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had ings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our present invention relates to a gas heating apparatus, and more fparticularly to an or use in hot air furnaces.

It is the object of our invention to provide a gas heating apparatus which is simple and economical in construction, and embodies the improved details ofstructure which will presently be fully described and ointed out in the claims, reference being ad to the accompanying drawings forming part of the s ecification, in which like reference numera s refer to like parts throughout the several views, and in which,

Figure I is a side view in central vertical section of an apparatus constructed accord ing to our invention shown applied to an ordinary hot air furnace. Fig. II is a view in cross section on the line IIII, Fig. I. Fig. III is a plan view of one of the lower burner cones. Fig. IV is a similar view of one of the upper burner cones.

. Referring more in detail to the drawings, 1 represents the outer casing, and 2 the fire bowl of an ordinary hot air furnace.

3 represents the grate flange in the fire bowl, the grate having been removed to facilitate the installation of our apparatus.

Supported on the fire bowl base 4 are the standards 5, which support the lower cone 6 of the bottom burner of our apparatus, which member is provided at its apex with a neck to the accompanying draw-,

On cone 11 arethe standardsS {which support the lower cone 6 of a second burner, cone 6 having a neck 7 inwhich is carried a tube 8 which extends downwardly through the lower burner and is provided with a hood 9.. Gone 6 is provided with lugs 10 and supports an upper cone 11, all of which parts are identical with the sim'lar parts comprising and connected with the lower burner, previously described. The upper cone 11 of the second burner in turn supports the standards 5 which carry a third burner comprising the lower cone member 6 having a neck 7" anda tube 8 which extends downwardly through the two lower burners and is provided with the hood 9 and which is also provided with the lugs 10 supporting the spreadingcone member 11" Supported on the upper members of each of the spreading cones are the baflie rings 12-12 -12 which extend beyond the peripheries of the cones andaid in securing a perfect combustion of the gases and in the difiusion of the heat.

Opening into the respective hoods on the tubes, depending from the spreading cones are the feed pipes 13-1313, which pipesare provided with separate cut-ofis and terminate in a manifold 14, which is connected with a main supply pipe 1 5.

When in use, the gas is turned on by opening the cooks in the separate feed pipes, an rises through the depending hoods and tubes into the chambers between the upper and lower cones of the various burners, and passing upwardly and outwardly along the under surface of the upper spreading cones, escapes through the peripheral outlet between the cone members into contact with the baffle rings sup orted on the spreading cones. After the supp y has been turned on, the gas from the lower burner is ignited, and the flame rising in the fire bowl ignites the gas flowing from the upper burners, heating the burner parts and the gas passing through the feed pipes so that the gas flowing to the upper burners 1s in a highly combustible condition when delivered thereto.

Another advantage of our construction is that the gases are burned in close proximity to the fire bowl so that the heat may be applied directly thereto for radiation into t e ot air jacket connecting with the heating pipes.

Having thus described our invention, what We claim as new-therein, and desire to secure by Letters Patent is In a gas heating apparatus, the combination with a fire-bowl, of a set of burners arranged one above the other within said fire bowl, each burner comprising a pair of inverted cone members spread apart to form a fuel chamber and a peripheral discharge opening, a feed pipe opening through the lower cone member of each burner and extending downwardly through the successive lower members, and a baffle ring supported on and projecting beyond the periphery of the lower cone member of each burner, substantially as and for the purpose set forth.

In testimony whereof we aifix our signatures in presence of two witnesses.

HIRAM G. STEELE.
